Following is a list of confirmed batteries that will fit in the 6HV with the canopy on. Thought I would try and make a neat and tidy list as the last topic to do this ended up needing the viewer to search and read through posts, hopefully will be able to make choosing and purchasing batteries easier. If there is anything you would like added (or changed if I have made a mistake) just post with that Brand, Capacity, Discharge Rate and Frames, and I will add to the list.

Fantastic resource, Andrew! I'm just sorry I don't have anything to add.

I already got your setup as I sneakily went through most of the 6HV battery topics and pulled what I could from them. So you infact did contribute!
If this gets good enough in your mind for a sticky would you like to do the honors?

Thanks mates. Also, I've not heard any mention of CG. is there room with Nano Tech 3000's to tweak for CG? I was thinking how nice it is once again to have an airfram unaffected by consumption of a pound of fuel from start to finish of a flight. I ran a rather big 3800 LiFe pack on my Fury 55 to get it right when the tank is half full.

CG changes from model to model as everyones layout is different. But the 3000 Nano-Techs allow for a decent amount of movement in the FBL Frames to compensate. (Which I assume you have?) I believe they are about the same size as the Turnigy 2650mAh 30C packs which is what I have and they can be moved a fair amount forward and aft.

The maximum dimensions are almost impossible to calculate (unless somone here is good with three dimensional conics).
This is because as the length on the battery pack changes, the allowed height/width of the pack changes as the shape of the canopy curves down.
So for a longer pack it will need to be not so tall and/or fat and for a shorter pack it can be taller and/or fatter.
